| Nitrocotton | 71 |
| Barium nitrate | 20 |
| Potassium nitrate | 5 |
| Camphor. | 3 |
| Binding material | 1 |
The nitrocotton has a solubility of only 15 or 20 per cent., and is partially gelatinised with ether-alcohol aided by the camphor. It is granulated under edge runners, granulated and drummed.
MACARIT.—A Belgian high explosive for filling shell—
| Trinitro-toluene | 30 |
| Lead nitrate | 70 |
It has a high density and is not deliquescent. For equal weights its power is less than that of trinitro-toluene or picric acid, but for equal volumes it is somewhat greater.
MARKANIT. See [SILESIA].
MARSIT.—A sort of Oxyliquit. Liquid oxygen is passed into a linen bag containing soot.
M.B. POWDER (Modernised Black) is a [black powder] mixture in which part of the potassium nitrate has been replaced by potassium or ammonium perchlorate, generally the potassium salt. It is manufactured at Bonnybridge, Stirling, at the works originally erected for making [Mitchellite]. During manufacture the composition is heated in steam boilers. (See “Arms and Explosives,” 1911, p. 7.)
